I can highly recommend A Line coaching, based in Sheffield. I had a course with them a few years ago and feel that it has definitely helped me get through that skills plateau which everyone reaches at some point.
John is a great bloke and used to guide for Ticket to Ride BC in Whistler. I did their Flow course as I wanted to improve my confidence in cornering. The day was based around Parkwood Springs, moving to Bowlhills and Greno later in the day. A couple of years on and I feel as though I’m a much more confident rider, and still practice many of the skills/techniques we covered on the day.
